Uniform convergence of an upwind discontinuous Galerkin method for solving scaled discrete-ordinate radiative transfer equations with isotropic scattering kernel
Qiwei Sheng, Cory D. Hauck
We present an error analysis for the discontinuous Galerkin method applied to the discrete-ordinate discretization of the steady-state radiative transfer equation. Under some mild…
Analysis of a new implicit solver for a semiconductor model
Victor P. DeCaria, Cory D. Hauck, M. Paul Laiu
We present and analyze a new iterative solver for implicit discretizations of a simplified Boltzmann-Poisson system. The algorithm builds on recent work that incorporated a sweepin…
Hybrid Solver for the Radiative Transport Equation Using Finite Volume and Discontinuous Galerkin
Vincent Heningburg, Cory D. Hauck
We propose a hybrid spatial discretization for the radiative transport equation that combines a second-order discontinuous Galerkin (DG) method and a second-order finite volume (FV…
Ray Effect Mitigation for the Discrete Ordinates Method Using Artificial Scattering
Martin Frank, Jonas Kusch, Thomas Camminady +1
Solving the radiative transfer equation with the discrete ordinates (S) method leads to a non-physical imprint of the chosen quadrature set on the solution. To mitigate these s…
A mathematical model of asynchronous data flow in parallel computers
Richard C Barnard, Kai Huang, Cory Hauck
We present a simplified model of data flow on processors in a high performance computing framework involving computations necessitating inter-processor communications. From this or…
Qualitative Properties of Mathematical Model For Data Flow
C. D. Hauck, M. Herty, G. Visconti
In this paper, properties of a recently proposed mathematical model for data flow in large-scale asynchronous computer systems are analyzed. In particular, the existence of special…
